SMOKING PIPE.

Application alea July 22, 1926, serial No. 124,211, and in 'Italy April 27, i926.

The present invention is concerned with improvements in smoking appliances, and while in its broader aspects the lnventlon is applicable to a cigar or cigarette holder,

it finds its preferred embodlment 1n alpipe.

An object of the inventionis to provide a slnoking pipe which will give a cool dry smoke, and in which the vaporou's nicotine and other highly volatile oils distilled from the burning tobacco will be trapped and condensed before reaching the mouth of the smoker, so that the smoke will be purified. 1n addition to cooling and purifying the smoke before it reaches the mouthpieceof the pipe, I 'provide lneans for entrapplng saliva which may enter the mouthpiece and prevent such saliva from being drawn back into the mouth of the smoker.

Further objects of the invention are to provide a smoking pipe of simple practical construction, which may be readily disassembled for purposes of cleaning or repair, a pipe which will be rugged, durable and efficient in use, and which may be manufactured with comparative economy.

A further object of the invention is to provide a pipe embodying the above noted advantageous features of construction, lyet simulating in appearance an ordinary pipe, the smoke cooling and conilensing and the salvia trapping means being wholly con-4 cealed within a coupling` member which connects the pi pe vbowl to the pipe bit.

lith the above noted and other objects in view, the invention consists in certain -novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claim.v rlhe invention may be more fully understood from the following description in connection with the accompanying drawings, wherein- Fig. 1 is a view partly in side elevation and partly in longitudinal section through a pipe embodying the present invention.

llig. 2 is a longitudinal view through the bowl.

Fig. 3 is a view in side elevation of the coupling member.

Fig. el is a view partly in side elevation and partly in section through the bit.

Fig. 5 is a longitudinal sectional view through the sleeve which conceals the coupling member.

F/ig. 6 is a longitudinal sectional View through the coupling member.

Flg. 7 is .a transverse sectional view on the line 7 7 of Fig. 6.

In the drawings I have used the reference character 10 to designate a pipe bowl formed with the usual smoke passage 1l therein. The bowl 10 is connected tothe' lbit 12 'of the pipe by a coupling member designated generally at 13. The smoke passage in the Vbit 12 has been numbered 14, and a sleeve encircling and concealing the coupling member 13'has been given the number 15..

The pipe bowl 10 is provided with a short extension 10a adapted for connection with the coupling member 13. To eEect such connection, the smoke passage 11 is prefer ably enlarged and tapped to define a threaded socket 16 into which sci'ews a threaded plug 17 on the coupling member 13. Coupling member 13 is of approximately frusto! conical shape, being formed with an annularl flange 18 at the elld of the plug 17, this flange abutting the end of the pipe bowl eX- tension 10a. Coupling `member 13 is exteriorly grooved at 19 to provide a tortuous passageway for smoke passing from the bowl to the bit.

As illustrated the groove 19 is of general spiral shape, and smoke in the course of its passage through the groove is caused to pass through a transverse opening 2O in the coupling member, which may be packed with a suitable wadding 21 of cotton or other material. A smoke passage 22 in the plug y17' connects with one end of the spiral groove 19,`and a smoke passage 23 at the other endof the spiral groove connects 'with a. second transverse passage 24; in an extension 25 of the bit 12.

At the end opposite the plug 17, the coupling member is internally socketed at 26 to define a saliva entrapping chamber into which the bit extension 25 isl frictionally tted.

lIn assembling the pipe, the opening 20 is filled with the cotton wadding; coupling member 13 is screwed into the bowl eXtension 10a; sleeve 15 slipped over the coupling member; and the bit frictionally fitted into the saliva pocket 26. A

The sleeve 15 co-operates with the groove 19 to define a tortuous air-cooled smoke passageway. Smoke .drawn from the bowl of eny 2 1,e54,ss4

the pipe is carried through this passageway and iltered through the wadding 21. In the course of such cooling and ltering'process, the highly volatile oils distilled from the tobacco will be vcondensed on the wadding, so that the smoke will reach the pipe bit in a thoroughly cool, dry condition.

Any saliva which may enter the bit 12 drains into the pocket 26 and is trapped until such time as the bit is removed from the coupling member. It may be noted in this connection that-the smoke passage 14 extends-all the way through the bit, so that the natural tendency of saliva in the passage- Way 14 is to drain into the pocket 26 and not clog up the smoke inlet passageway 24.

Obviously, various changes and'alteratio'ns might be'made in the general form and ar-V rangement of parts described without departing from the invention. Hence I do not wish to limit myself to the details set y forth, but shall consider myself at liberty to make such changes and alterations as `fairly fall within the spirit and scopeof the appended claim.

I claim:

A smokingpipe including a bowl, a bit, a smoke purifying and oil condensing element connecting the bowl and the bit, a sleeve encircling and concealing said elelnent, said element having a saliva receiving pocket therein communicatingl with the end of the smoke passage in the bit and into which the bit is fitted, and a smoke ycooling passageway therein communicating with the smoke passage in the bit at' a. point removed from the union of this passage with the saliva receiving pocket, whereby a draught of smokeladen air is drawn directly through the condensing element into the bit without passing through the saliva pocket.
